Nigerian soldiers shot at a crowd of protesters, killing quite a few, after some started throwing rocks.

Officials said they were getting their human rights guidance from the bullshitter.

Rocks are weapons, but not very effective weapons, especially when thrown by hand by people without special training. (Since they cited David and Goliath, keep in mind that David reportedly used a sling to throw the rock hard, and had trained his aim through hunting.) The soldiers were presumably protected by armor including helmets, and in hardly any danger. They should have held their fire.

This shooting is likely to lead to worse violence.
